CVE-2022-44753
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedHCL Notes is susceptible to a stack based buffer overflow vulnerability in wp6sr.dll in Micro Focus KeyView. This could allow a remote unauthenticated attacker to crash the application or execute arbitrary code via a crafted WordPerfect file. This vulnerability applies to software previously licensed by IBM.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA stack-based buffer overflow vulnerability exists in wp6sr.dll (Micro Focus KeyView) used by HCL Notes. Remote unauthenticated attackers can exploit this by delivering a crafted WordPerfect file, potentially causing application crashes or arbitrary code execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify HCL Notes installationLocate HCL Notes installation directory - typically under Program Files (x86)\HCL or Program Files\HCL on Windows. Check for notes.exe or related executables.Affected if HCL Notes is not installed on the system
-
Check HCL Notes versionOpen HCL Notes and go to Help > About HCL Notes, or right-click notes.exe and view Properties > Details for version information. Compare against affected versions 9.0.1 and 10.0.1.Affected if Installed version is exactly 9.0.1 or 10.0.1
-
Confirm WordPerfect processing is enabledCheck Notes configuration for KeyView filter settings. Look for WordPerfect (.wpd) file association handling or KeyView plugin status within the Notes data directory.Affected if WordPerfect file processing or KeyView filtering is enabled in Notes configuration
-
Locate vulnerable wp6sr.dllSearch for wp6sr.dll within the HCL Notes installation directory and subfolders, particularly under the KeyView or plugins directories.Affected if wp6sr.dll exists in the Notes installation and version matches vulnerable KeyView component
User is affected only if HCL Notes version is exactly 9.0.1 or 10.0.1 AND WordPerfect file processing via KeyView is enabled, with the vulnerable wp6sr.dll present.
